L293D Motor Driver Shield for Arduino
The L293D Motor Driver Shield for Arduino is a versatile tool for various robotic projects. It features two servo connectors and four motor connectors, supporting both DC and stepper motors. Utilizing the L293D chip, it drives the motors while using Arduino pins 9 and 10 to control the servos.
The L293D is a 4-channel driver capable of handling high voltage and current, supporting DC motors and power supplies up to 36 volts with a maximum output of 600mA per channel. As an H-Bridge, it allows voltage to be applied in either direction, making it ideal for motor control.
This shield includes two L293D motor drivers and a 74HC595 shift register, which expands three Arduino pins to control eight motor driver outputs. The enable outputs of the L293D are directly connected to the PWM outputs of the Arduino for enhanced control.
Features:
- Versatile Compatibility: Capable of running 2 servos, 2 steppers, or 4 DC motors with external power supply control via Arduino.
- Servo Support: 2 connections for 5V ‘hobby’ servos, utilizing Arduino’s high-resolution dedicated timer.
- Motor Control: Equipped with 4 H-Bridges powered by the L293D chipset, providing 0.6A per bridge (1.2A peak) with thermal shutdown protection and internal kickback protection diodes.
- Wide Voltage Range: Supports motors operating on 4.5VDC to 25VDC, offering flexibility in power supply options.
- Precise Speed Selection: Individual 8-bit speed selection for up to 4 bi-directional DC motors, providing approximately 0.5% resolution.
- Stepper Motor Compatibility: Capable of controlling up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, or interleaved stepping.
- Safe Operation: Pull-down resistors keep motors disabled during power-up, ensuring safe and reliable operation.
- Easy Connectivity: Features big terminal block connectors for convenient wire hook-up (18-26AWG) and power connection.
- Arduino Compatibility: Tested and compatible with Arduino Mega 1280 & 2560, Diecimila, Duemilanove, and UNO boards.
- External Power Option: Includes a 2-pin terminal block and jumper for connecting external power, ideal for separate logic/motor supplies.
